Heat olive oil in a skillet over medium heat. Add finely diced onions and sauté until translucent, about 2 to 3 minutes. Crumble sausage into the pan and cook, breaking it up, until lightly browned and heated through. Stir in dried thyme and Dijon mustard until well combined. Remove from heat and let cool slightly.

Unroll crescent roll dough onto a flat surface. Separate into 8 triangles along perforations. Gently stretch each triangle if needed to widen for filling.
03 -
Place a heaping tablespoon of sausage filling on the wide end of each dough triangle. Roll tightly from the wide end, tucking in sides to fully encase filling. Arrange rolls seam-side down on a parchment-lined baking sheet.

Brush each roll with beaten egg to ensure a glossy, golden crust. Bake at 375°F for 13 to 15 minutes, or until rolls are puffed and deep golden brown.

Allow rolls to cool slightly on a rack before serving. Serve warm for optimal flavor and texture.
